PAPER-FOLDING MACHINE.

Application filed May 15, 1924. SeriaI No. 713,495.

To all whom it may concern:

Be it known that I, WALTER G. TRAUT- MAN, a citizen of the United States of America, residing at Cleveland Heights, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a specification.

My invention relates to improvements in paper folding machines, and has for its ob ect the provision of means adapted alternatively for folding signatures or for transferring them unfolded to another position within the machine.

My improvements may best be described as associated with a paper-folding machine adapted to deliver the partly folded signatures to the auxiliary mechanism of my present improvement. This mechanism comprises a folding plate normally open from end to end, associated with folding and buckling rolls and with a second folding plate, if so desired, which first named folding plate is adapted for conversion in order to transfer the signatures to another portion of the folding machine, as upon a conveyor table associated with the open end of said folding plate. A removable stop device is provided for employing the folding plate 111 the ordinary manner to fold the signatures and thereafter deposit them upon a stacker device.

The details of my improvements may best be explained by making reference to the accompanying drawings, wherein Figure 1 is a longitudinal sectional-view,

partially diarammatic in character, illustrating the features of my improvement when employed for completing two final folds of a signature.

Fig. 2 is a similar fragmentary view, terminally broken away, showing the apparatus as adjusted and employed to convey the unfinished signatures to another portion of the machine.

Fig. 3 is a similar view illustrating the substitution of a deflector and an adjustment for rendering the folding plates inoperative;

Fig. dis a fragmentary side view of my improved mechanism, terminally broken away,

Fig. 5 is an "enlarged fragmentary plan view illustrating the details of the convertihle folding plate and Fig. 6 is a view thereof in side elevation partially in section.

Throughout the several figures of the drawings I have employed the same character'of reference to indicate similar parts.-

Referring first to Fig. 1, the feeding rolls a a of'the associated paper-folding machine are shown in position for passing the signatures tothe conveyor table a of my im proved auxiliary apparatus. This conveyor table is adapted to pass the signatures to the set of folding and buckling rolls d e f and g with which are associated the folding plates '72. and 5. Normally, these folding plates operate in the usual manner to produce successive transverse folds in the signature which is then passed beneath the deflector j and through the feeding rolls Jr is to the driven belt Z of the stacker device shown at the left.

However, these folding plates h and z are adapted to be rendered inoperative as such appliances, under certain conditions of use, as will now be explained. Thus, it vf'ill be observed from Fig. 2 that the folding plate 86 2' is open from end to end; bein provided with a removable stop device i which is adjustably mounted u on the....longitudinally movable rods 2" When the sto device is disposed as shown in Fig. 2 an i the coacting rolls 7: i mounted in the pivoted frame i are adjusted to engagethe upper rolls m m, it will be seen that the folding plate 71 is rendered inoperative as such, since the I signatures will be passed therefrom and through the feeding rolls n n to the secondary conveyor table 0 for transfer to another ortion-ofthe paperfolding machine. This permits the forming of a single fold in the auxiliary mechanism @5 of my present invention while further folds at right angles to those produced "in my auxiliary mechanism may be made, for example, in ap aratus beyond the secondary conveyor ta 1e but not herein described or shown. This adjustment affords the principal advantageous use of my auxiliary mechanism; eifecting either one or two transverse folds in the signature. I

An additionaladjustment of which my improved apparatus is capablewill be explained in connection with Fig. 3 wherein it will be seen that the folding plate It and the folding roll f are respectively elevated out of their normal operative positions in no accordance with the improvements claimed in my co-pending application, Ser. No. 713,719. The deflector member ,0 is substituted therefor in association with the adjustable deflector j, so that the signatures will be passed from the rolls (Z 6 directly to the feeding rolls 7; 7; and through them to the stacker device upon the left. This adjustment, it will be seen, renders both of the folding plates inoperative so that the signatures are taken directly from the conveyor table 0 to the stacker device without imparting a fold thereto. Thus, three different functions are provided for in the auxiliary mechanism which are principally contributed to by the conveying folding plate 1' equipped with the adjustable conveyor rolls and stop device previously described.

Having now described the preferred embodiment of my invention and briefly detailed the operation and advantages thereof, I claim as new and desire to secure by Letters Patent the following:

1. In mechanism of the class described, the combination with folding and buckling rolls of a folding plate open from end to end and operatively associated therewith, a stop device adapted to be actuated into positions for deflecting the signatures through the folding rolls, and signaturereceiving means disposed adjacent to both ends of said folding plate, substantially as set forth.

2. In mechanism of the class described, the combination with a set of folding and buckling rolls, of two coacting folding plates operatively associated therewith; the second of said folding plates being open from end to end, a stop device adapted to be actuated into positions for deflecting the signatures from the latter folding plate through the folding rolls, and signaturereceiving means disposed adjacent to both ends of the second folding plate, substantially as set forth.

In mechanism of the class described, the combination with a set of folding and buckling rolls, of two coacting folding plates operatively associated therewith; the second of said folding plates being open from end to' end, a stop device adapted to be actuated into positions for deflecting the signatures from the latter folding plate through the folding rolls, signature-receiving means disposed adjacent to both ends of second folding plate, and a deflector appliance adapted to be substituted for the first remap named folding plate, substantially as set forth.

at. In mechanism of the class described, the combination with a set of folding and buckling rolls, of two coacting folding plates operatively associated therewith; the second of said folding plates being open from end to end, a stop device adapted to be actuated into positions for deflecting the signatures from the latter folding plate through the folding rolls, a stacker device associated with the folding and buckling rolls and a conveyor table associated with the open end of the second folding plate, substantially as set forth.

5. In mechanism of the class described, the combination with folding and buckling rolls, of a folding plate open from end to end operatively associated therewith, a stop device adapted to be actuated temporarily into positions for deflecting the signatures through the folding rolls, and conveying rolls alternatively operative for directing the signatures through the folding plate, substantially as set forth.

6. In mechanism of the class described, the combination With a folding plate open from end to end, of a stop device adapted to be actuated temporarily into positions for deflecting the signatures from said folding plate, and adjustable conveyor rolls adapted alternatively to act upon the signatures for passing them through said folding plate, substantially as set forth.

7. In mechanism of the class described, the combination with a folding plate open from end to end, and adjustable stop device therefor, and a set of conveyor rolls adapted alternatively with said stop device to act upon the signatures entering said folding plate, substantially as set forth.

8. In mechanism of the class described, the combination with a set of folding and buckling rolls, of two co-acting folding plates associated therewith; the second of said folding plates being open from end to end, a stop device adapted to be actuated into positions for deflecting the signatures from the latter folding plate through the folding rolls, adjustable conveyor rolls adapted alternatively to act upon the signature entering said folding plate, and signature-receiving means disposed adjacent to both ends of said folding plate, substantially as set forth.

In testimony whereof I do now allix my signature.
